SHUTTLE-BOX non Looms.

To all whom itma z concern;

. Be it known that we, ALVIN KINGsBAQI-nm and WALTER MAorA nn ,oitiaensfof the United States, residing at Pittsburgh, inthe county of Allegheny and. State of .Pe111isyl- Vania, have invented certain new and useful Improvements in Shuttle-Boxes for Looms, of which the following is. a specification. Our invention relates to looms. and more specifically to means for weaving two fabrics at once .each having varicolored threads'in the filling, wherebywany desired patterns can be woven and the production of the loomisgreatly increased. e The objectof our invention is to provide means for passingtwo shuttles through two separate sheds at the same time, andto provide means for changingthe shuttles at will for others containing different colors according to the requirements of the pattern.

To these ends our invention consists in a rotary shuttle boX which may be applied to either or both sides of the,loom, means for rotating the shuttle box between picks to present the desired shuttles simultane ously and a selectivelatoh mechanism for the shuttle,box controlled by the pattern chain, together with thevarious details of construction shown.- in" the drawings, in

Which: i i m Figure 1 is a sectional elevation through the shuttle box showing the picker, etc. Fig. 2 is a plan view of thesame. t Fig. 3 is a sectional elevation on the line l l of Fig. 2. i 1 1 i a Fig. 4: is an elevation of. the shuttle box. Fig. 5 is a cross section of oneof th pockets for the shuttles. a e

Fig. 6 is a diagrammatic planviewof the pattern chain forthe filling. a

Fig. 7 is a diagrammatic elevation showing the shuttle box in relation to the double shed in thewarp. I g l The general construction of looms and their method of operation .beinga matter of common knowledge, we. have shown only those parts necessary to an understanding of our invention, and .asour improved mechanism may be applied to a variety of looms, and may assume a variety of forms, We have represented the same merely diagrammatioally. a y 1 Referringto the drawings the shuttle box 1 Specification of Letters Patent.

lisinounted to rotate freely on the pin 2, supported by the lay sword 3, which is secured to the lay shaft 60.- a

e The shuttle to 1 is provided with two series of concentric pocketsll and 5 to hold the shuttles. Each pocket is provided with a P il of SPringslG toicheck and hold the shuttle. (see Fig. 5);.

Aslot 7 isformed in the partition 8, be-

tween. boxes 4, and y 5, and a similar slot 9 1s formed in the outer wall of the box 5.

l A picker .11 is mounted to slide on a square E guidebar12 secured 11011118 sword 3, and is provided with a long hub 13, which assures rigidity. l

. The picker stick 14.is pivoted on a pin16 fastened to the layshaft 60 and actuated by the usual rod 17 andspring 18, and is connected to the picker 11;. by thelink 19. The picker 11 passes through the slots land 9 to actuate the shuttles 10.

A friction band 20 is secured to the shuttle box 1 the sameextending aroundthe outer circumference thereof and covering one end of fthe'slots 9. The band 20 is engaged at. suitable times by either of a pair of. friction Wheels 21. and 22, the same being mounted in pivoted frames. 23and24c, and driven by oppositely moving belts 25 and 26, or in any e The wheel 22 is brought into contactwith the band 20 by the pattern chainBl. The frame 24: is pivoted on the pin 27,.and swung by a vertical rod i.

28. which works in a guide 29, and is provided with a shoe 30,.which latter maybe engagedbytsuitable risers on the pattern chain 81. Similar means operate the frame 23 toengage the wheel 21.. i i .l

The :pattern chain 31 is composed of the side links 32 and pins 33 (shown in dotted lines in Fig. 6) and is. divided into Sspaces crosswise. These spaces may contain risers 34: or sinkers35 as usual. The first six spaces A to F areto operate the latch mechanism to be hereinafter described,.and the other two spaces G and H are to. operate thewheels21 and 22. a l U The chain 31 may travel over. a rigid guide 36, andwhena riser in space H strikes the shoe 30. the wheel 22 isforced into frictional contact With the band 20. This contact lasts only .while the riser passes under the shoe 30, andthe length of the shoe may bemade to suit the desired interval of contact.

A weight 37 on rod 28 returns the parts to an; inoperative position, and similar means actuated by risers in space G of chain 31 actuate the wheel 21.

If desired the shuttle box 1 could bero= tated by a single wheel 21 or 22, the other being'omitted, but in this case the operation would be slower, as the box 1 would have to be turned at times two-thirds andfive-sixths of a revolution, whereas in the the width of the drum 40, is divided into 6 equal spaces (or as many as there are pockets 4 or 5) Each division of width on the drum 40 is provided with a single notch 41, these notches being setaround the circumference at the same angular spacing as the pockets 4 and 5, and eachnotch-controlling a pair ofpocke'ts.

When the shuttle'box 1 is rotated by the wheels 21 or 22, it is-only necessary to allow a latch to enter the notch 41- corresponding to the pair of pockets 4and 5 from which the shuttles are to" bedrawn, in order to register'the shuttles with the warp.

A stationary shaft 44 carries six loosely mounted latches each connected by a link 4'6to a bell crank 47. i A set of "six vertical rods 48' is mounted in guides49 and 50, and each: rod 48 is provided with a hook 51 at itsflupperend, each of said hooks controlling a' latch 45. l

. Each rod 48 carries a strong spring 52 which normally causes the partsto assume the position shown in Fig. 3 with the collar 53 resting on the guide 50. Each rod 48 carries a shoe 54 which may be engaged by a riser in spaces A to F of chain 31.

Such" a riser will lift the corresponding rod 48 against the resistance of the strong spring'52 and allowthe weaker spring 55 to draw the latch 45 against the circunr ferenceof the drum 4'0;

As soon as the corresponding notch 41 comes opposite. the latch 45 the end thereof will enter the notch and lock the shuttle box 1 inisu'clr positi'oir that two of the shuttles- 10'will be in proper alinement with the lay.

As soon as the riser has passed the shoe 54- the spring 52 will Withdraw the atch 45 from the notch 41' and at the same instant or slightly before, the wheel 21 (or 22) will be brought to bear on the band 20 to rotate the box again.

It will be seen that the risers and sinkers in the various spaces (width) of the chain 31 perfectly control the operation of the shuttle box 1. When it is desired to repeat a pickseveral times from the same shuttle several risers are placed in the proper latch space (A to F) in consecutive order, and the shoe 54 is made long enough to span the space between adjacent risers so that the latch 45 may remain stationary during the desired number of picks.

When this is done consecutive sinkers are placed in the spaces G and H and the wheels 21 and 22 are-inoperative as regards the shuttle box 1.

The above description does not take account of the movement of the lay. The shuttles are changed in the forward position' of the lay, and the latches 45 engage the drum 40 in this position. When the lay starts back the shuttle box 1 and drum 40 are moved away from the latches thus disengaging the particular latch engaged.

In order to hold the shuttle box from turning during the movement of the lay, we provide a -friction brake operated by the movement of the lay as follows:

A brake block 61 is mounted on a lever 62' the latter being pivotally mounted on a pin 63 and connected to a strong spring 64. A stop 65 limits the motion of the lever 62 so that in the extreme forward position of the lay, the brake block 61 is out of contact with the drum 40 and the shuttle box 1 is free to rotate. As soon however as the lay starts back the drum 40 engages the block 61 and carries it along in contact; against the resistance of the spring 64 thus locking the shuttle box 1 against rotation and preserving the setting given it by the latches.

Fig. 7' shows the relations of the lay, the shuttle boxes, the reed and the sheds in the rear position of the lay. From spool 67 the threads 68 and 69' are led over the whip roll 70 to formthe upper shed 71. The thread 68 passes through the upper eye of the heddle 72 and the thread 69 passes through the upper eye of the heddle 73. These threads form the warp of the upper fabric 74. From spool 75 the threads 76 and 77 are led over the whip roll 70 to form the lower shed 78. ,The thread 76 passes through the lower eye of the heddle 72 and the thread 77 passes through the lower eye of the heddle 73 these two threads forming the warp of the lower fabric 79. Temples are indicated at 80 and 81.

hen the heddle 72 is depressed the thread 68 assumes the position shown for thread 69, and the thread 76 that shown for 77. At the same time the heddle 73 is raised and the thread 69 assumes the position shown for thread 68 and thread 77 rises to position shown for thread 76.

Thus the threads 68 and 69 cross each other and the threads 76 and 77 cross each other but neither pair interfere with the other thus weaving two independent fabrics. The reed is indicated at 68.

While the prime object of our invention is to provide means whereby the shuttles may be changed between picks and in any desired order so that two fabrics may be woven at once, each having a variety of colors in the filling it will be obvious that by omitting or not operating certain parts of the mechanism, our improved shuttle box may be used on a loom weaving cloth with but a single color in the filling and our improved shuttle box may be used in this case merely as a means of quickly replacing empty shuttles with full ones.

When so used the full shuttles could be introduced say at the top of the shuttle box.

The operation of our improved mechanism will be readily apparent from the above description to those skilled in the art.
